The objective of this work was to evaluate the influence of sodium dichloroisocianurate (NaDCC), ethylic alcohol, and sodium hypochlorite sanitizers, on the quality of 'Itália' grape, based on the physical and chemical characteristics. Clusters of 'Itália' grape harvested in São Miguel Arcanjo (SP) were selected by size and quality and submitted the postharvest treatments by immersion in ethylic alcohol solution (15% v/v), sodium dichloroisocianurate (200 ppm), and sodium hypochlorite (200 ppm) for 3 seconds and 10 minutes, respectively under ambient room conditions (21.2 °C; 69.8% HR) for 9 days. The clusters weight loss, tax of degrane, coloration, firmness, contents of soluble solids (SS), and titratable acidity (TA), SS/TA relation and pH of the berries were evaluated every three days. Under those conditions, the highest daily average mass loss was found in the sodium hypochlorite (0.7333%/day) followed by the non- sanitized clusters (0.6163%/day), sodium dichloroisocianurate (0.5837%/day), and ethylic alcohol (0.5623%/day). The berries sanitized with sodium dichloroisocianurate were darker and yellow. The sanification differences regarding firmness, pH, contents of soluble solids and titratable acidity, and SS/TA relation were not verified. From the results it can be concluded that the sanitizers do not influence in the physical and chemical qualities of 'Itália' grape.
